If government hides information to avoid public criticism, which democratic strength becomes weak?

Correct answer: Accountability and pressure of public opinion

The direct answer is B: accountability and pressure of public opinion. In a democracy, people need information about government actions so that they can discuss them, criticise mistakes, and demand explanations. The reasoning is: information becomes available; citizens form an informed opinion; they question or criticise the government; the government must answer and may correct its action. If information is hidden merely to avoid criticism, this whole chain becomes weak. Option A, hereditary power, means rule passed through a family; hiding information does not make democracy hereditary. Option B is correct because public criticism and informed opinion make rulers accountable. Option C, military discipline, concerns obedience in the armed forces, not democratic control. Option D, one-sided command, is the opposite of open democratic discussion. Memory cue: information plus criticism leads to accountability.
